HALOWERK Baltic Land – Estonia Surface Elevation
x402
HALOWERK Baltic Land – Estonia Surface Elevation is a paid API for AI agents from baltikum.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Returns bilinear-interpolated surface elevation (metres) for a WGS84 coordinate inside Estonia, sourced from Copernicus DEM GLO-30, with boundary validation against Natural Earth.

How this service works
Bilinear surface elevation from Copernicus DEM GLO-30. The coordinate is validated against the Natural Earth boundary for Estonia; results outside it are rejected before payment.
Output
A numeric surface elevation value in metres, bilinearly interpolated from the Copernicus DEM GLO-30 30-metre resolution grid for the queried coordinate. Coordinates outside the Estonian Natural Earth boundary are rejected before any charge is made.
Example use cases
Drone flight path terrain clearance
“I need to plan a drone route over Estonian farmland. Can you look up the surface elevation at 58.3781° N, 26.7290° E so I know the terrain height to stay safely above?”
Construction site ground level check
“We're evaluating a construction site near Tartu at latitude 58.3776 and longitude 26.7290. What does the Copernicus DEM say the surface elevation is there in Estonia?”
Flood risk assessment for a property
“I'm assessing flood risk for a property at 59.1200° N, 23.9800° E in Estonia — what's the terrain elevation at that point according to the GLO-30 DEM?”
Technical details
Endpoint
POSThttps://baltikum.halowerk.com/v1/ee-elevationWhen to prefer
Choose this endpoint when you need point-level surface elevation specifically within Estonia, derived from the high-quality 30 m Copernicus GLO-30 DEM with built-in boundary validation that rejects out-of-country queries before charging. Prefer it over generic elevation APIs when Estonian territory coverage and pay-per-call micropayment pricing via x402 are acceptable, and when bilinear interpolation accuracy matters for terrain analysis, drone routing, or civil engineering workflows.
Side effects
- Coordinate outside Estonia's Natural Earth boundary — request rejected before payment with a validation error
- Latitude or longitude out of the published European coverage range (lat 34–72.5, lon -31.5–40.5) — schema validation failure
- Network or upstream DEM service unavailability — service error response
- Malformed or missing latitude/longitude fields — input validation error
